Problems solved by technology

The absorption cannot be sustained due to the limited absorption capacity of the accumulator
[0006] In any of the above cases, the capacity of the VVVF energy storage device cannot be fully used
That is, it cannot effectively absorb

[0027] figure 1 is an external view showing an electric vehicle including the electric vehicle control apparatus according to the first embodiment of the present invention.

[0028] Such as figure 1 As shown in , the electric vehicle 10 receives power from the overhead line 21 through the pantograph 1 . The received electric power is input to the electric vehicle control device 20 .

[0029] figure 2 is a block diagram showing the configuration of the electric vehicle control device 20 .

[0030] The electric vehicle control device 20 includes a pantograph 1 , a contactor 2 , a filter reactor 3 , a VVVF inverter 4 , a DC / DC converter 6 , a motor 7 , a reactor 8 , wheels 9 and an energy storage device 11 . Assume V F , V D and V E are the voltages applied to VVVF inverter 4, DC / DC converter 6 and energy storage device 11 respectively, I E is the current flowing from the DC / DC converter 6 to the energy storage device 11 .

[0042] An electric vehicle control apparatus according to a second embodiment of the present invention will be described below with reference to FIGS. 6-8. The same reference numerals as in the first embodiment denote the same components in the second embodiment, and detailed description thereof will be omitted.

[0043]The difference between the second embodiment and the first embodiment is that the detection / control device 4a of the VVVF inverter 4 does not output any information to the detection / control device 6a of the DC / DC converter 6, and the DC of the energy storage device 11 The absorption starting voltage value V3 of the filter capacitor voltage value 101 of the / DC converter is set in advance to be equal to the operation starting voltage setting value (regeneration limiting starting voltage value) V1 of the filter capacitor voltage value 100 .

[0048] Refer below Figure 9 and 10 An electric control device according to a third embodiment of the present invention will be described. The same reference numerals as in the first embodiment denote the same components in the third embodiment, and detailed description thereof will be omitted.

[0049] The third embodiment differs from the first embodiment in that the information output from the detection / control device 4a of the VVVF inverter 4 to the detection / control device 6a of the DC / DC converter 6 is different from the regenerative braking throttle amount information 103.

[0050] The DC / DC converter 6 also includes a predetermined value detection unit 6b. The predetermined value detection unit 6b outputs a correction command for correcting the absorbing start-up voltage value V3 to a voltage value V3' to the detection / control device 6a of the DC / DC converter 6 according to the input regenerative braking restraint amount information 103 (see Figure 10 ). The pred...

Abstract

An electric motor control apparatus including an inverter (4) which drives a motor of an electric motor car, storage unit (11) for storing energy for the motor (7), and a converter which is connected to the storage unit (11), the inverter (4) comprising detection unit for detecting a power value of the motor (7), and transmission unit for transmitting the power value detected by the detection unit to the converter (6), and the converter (6) comprising calculation unit for receiving the power value transmitted by the transmission unit, and calculating an absorption current on the basis of the received power value, and control unit for controlling the storage unit (11) on the basis of the absorption current calculated by the calculation unit.

Description

technical field [0001] The invention relates to an electric vehicle control device. Background technique [0002] According to the general technique of series connection of electric double layer capacitors in railway vehicles as disclosed in Japanese Patent Application KOKAI Publication No. 2003-18702 and "A Study for Electric Double Layer Capacitor Series Connection for Railway Contraction", 2003 JIASC Conference 3-32, using So-called regenerative limiter control is performed using the technology of the VVVF inverter (inverter). The regeneration limitation control is performed as follows. When the VVVF inverter is set, during regenerative braking, in a light load regeneration state where the load to absorb the regenerative energy on the overhead line side becomes insufficient, a rise in the capacitor voltage of the VVVF inverter is detected The increase in the overhead line voltage suppresses the increase in the overhead line voltage by reducing the regenerative braking f...
